Heart disease showdown: surgery vs. pills over 10 years
NCT ID NCT04894877
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows over 5,000 people with stable heart disease who were previously treated with either an invasive strategy (like stents or bypass surgery) plus medication, or medication alone. Researchers want to see which approach leads to better survival over 10 years. The goal is to give patients and doctors clearer information on the best long-term management for coronary artery disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could provide clear evidence on whether an initial invasive strategy (stents or bypass surgery) or medical therapy alone is better for long-term survival in stable heart disease patients.
- What could go wrong
- This is an observational follow-up of a completed trial, not a new treatment test. Results may show no clear difference between strategies, and findings may not apply to all patients.
